Before she was committed, the 28-year-old actress removed the allegations she made against her father on Twitter.

'In a rare moment of clarity before Amanda became a patient at the mental health facility in Pasadena, she actually deleted the posts on Twitter accusing her father of sexually abusing her,' Radar's source added.

'No one else but Amanda did it.'

The source with People claims: 'When she is in one of these states, her anger and frustration is directed towards her father.'

Meanwhile it emerged on Saturday that Amanda's claims that she was getting married to aspiring actor Caleb Pusey were false.

On Wednesday, she surprised her Twitter followers by announcing her engagement.

She posted: 'I am getting married and my boyfriend and I are going to be on the cover (sic) People magazine.'

But TMZ said the 19-year-old, who acknowledges meeting Amanda during her previous stint in a treatment center, had never dated her and had not spoken with her in months.

In a brief and rambling interview with In Touch magazine last week, Amanda said: 'I am very needy for friendship and I hate men. I want to f*** them, but I can now say I’m engaged.

'I want to be married and I want to be away from people.'

And she added that she wanted to start a family. 'I want boys, for sure. However many I can pop out,' she said.

Amanda shot to fame at the age of 10 in 1996 with role in hit TV show All That and Nickelodeon's Figure It Out.

At 13, touted as America's rising star in both comedy and acting, she was given her own sketch show: The Amanda Show.

But her troubles began in 2010, then aged 24, after she announced she was retiring from acting and appeared in a racy photo shoot for Maxim magazine, insisting 'this is me'.

It was an apparent bid to break from her child-star image.

In the following four years, she was arrested for DUI, accused of crashing into a police car and another motorist, pictured taking drugs, allegedly banned from a number of establishments for 'erratic behaviour', and in 2013 placed in involuntary psychiatric care.

Last week her life appeared to be spiraling once again when was arrested in LA for DUI.
